Question

所以我的问题与其他问题有点不同。对于其他人，他们直接使用Response.Redirect( url );，因此修复程序只是围绕着它。

但是，我在同一个控制器中有类似的内容：

public ActionResult Index()
{
  // some other logic running inside this function...

  return RedirectToAction( "Result" );
}

public ActionResult Result()
{
   // Expecting calls being sent from Index

  return View ("done");
}

所以我并没有直接调用Response.Redirect（），但RedirectToAction（）最终可能会调用Response.Redirect（）。在这种情况下，我该怎么办？

这些是堆栈跟踪：

Answer 1

在Response.Headers.Clear()

之前致电RedirectToAction

在执行RedirectToAction（）时“在发送HTTP标头后无法重定向”
